Abstract

A method for securing a first housing member to a second housing member of a device, includes affixing a set of tape adhesive portions to a first section of a perimeter of the second housing member and distributing a liquid adhesive to a second section of the perimeter of the second housing member. The method further includes compressing the liquid adhesive into at least one compressed liquid adhesive portion to create a sealant for securing the first housing member to the perimeter of the second housing member, wherein the sealant comprises the set of tape adhesive portions and the at least one compressed liquid adhesive portion.

First claim

We claim:

1. A method for securing a first housing member to a second housing member of a device, the method comprising:
affixing a set of tape adhesive portions to a first section of a perimeter of the second housing member;
after affixing the set of tape adhesive portions, distributing a liquid adhesive to a second section of the perimeter of the second housing member, while leaving a gap between a first end of at least one of the tape adhesive portions and a second end of the distributed liquid adhesive along the perimeter;
after distributing the liquid adhesive, compressing the liquid adhesive into at least one compressed liquid adhesive portion, wherein the compression causes the liquid adhesive to flow into, and close, the gap between the at least one tape adhesive portion and the liquid adhesive, and to create a sealant for securing the first housing member to the perimeter of the second housing member, wherein the sealant comprises the set of tape adhesive portions and the at least one compressed liquid adhesive portion.

2. The method of claim 1 , wherein the perimeter comprises a total length around an edge of the second housing member, and wherein the set of tape adhesive portions is affixed and the at least one compressed liquid adhesive portion is distributed end-to-end with each other along the total length of the perimeter to have the sealant continuous along the perimeter.

3. The method of claim 1 , wherein each compressed liquid adhesive portion comprises a first end and a second end that each join with a different end of at least one of the tape adhesive portions, wherein the joining is along a total length of the perimeter of the second housing member.

4. The method of claim 1 , wherein at least one of the tape adhesive portions is affixed to the perimeter of the second housing member and surrounds an electronically sensitive part of the device in a plane of the second housing member to prevent at least one of the compressed liquid adhesive portions from extending into the electronically sensitive part of the device.

5. The method of claim 1 , wherein the first end of the at least one tape adhesive portion has a V-shaped geometry with a vertex of the V-shaped geometry pointing along the perimeter toward the second end of the uncompressed distributed liquid adhesive and with the vertex of the V extending into the distributed liquid adhesive after the distributed liquid adhesive has been compressed.

6. The method of claim 1 , wherein the set of tape adhesive portions is affixed to control a height of each compressed liquid adhesive portion, wherein the height is relative to a plane between the first and second housing members.

7. The method of claim 6 , wherein the set of tape adhesive portions is affixed to control the height of each compressed liquid adhesive portion to be equivalent to a height of the tape adhesive portions.

8. The method of claim 1 , wherein at least one of the tape adhesive portions is affixed to a region of the perimeter of the second housing member having a dimension along the perimeter that is less than a dimension of the distributed liquid adhesive of each compressed liquid adhesive portion.

9. The method of claim 1 , wherein at least one of the tape adhesive portions is affixed to a region of the perimeter of the second housing member having a dimension along the perimeter that is less than a minimum dimension along the perimeter of each compressed liquid adhesive portion.

10. The method of claim 1 , wherein at least one of the tape adhesive portions is affixed to a region of the perimeter of the second housing member associated with a higher probability of detachment or breakage when the device impacts a surface.

11. The method of claim 10 , wherein at least one of the tape adhesive portions is affixed to a corner region along the perimeter of the second housing member.
